Be it known thatI,4 4W'ILERID LUMLEY, a

citizfenofthe UnitedSta-test'ltesidin atEast.

Conneaut, i n the'connty .of .Ashta ula. andv Stateof Ohio, Vhave invented a certain, new',

, and .useful Improyement'inDomes for Illuminating-Fixtures, of which the following is fixturesi a fullyclear7 andfexact description.

' The object .of the. present invention is to' provide an t improvement in gas :and electric `more particularly in the large deco- 'rative omes usedfor chandeliers and similar lights.

The invention isdirected broadly to a. constructionrof dome which shall. b e capable of. decorative eectscqualto or superior to ,i those lmdbythe prior construct ions and. yet

i bereadilytakenapart andpacked within a V small` s acethus" decreasing the cost of stor-y f L i age an l-,shipment It has further been myobject to achievey thev Vabovedescribed results without impair-' inggthe rigidity or strength of the dome in any manner.

" Tlxeggabore named advantages .and other` vdesirableends, it will he seen, are obtained `hythe invention which, -I have produced, an

embodiment of wh icl1`v isdescribed inthe. `following specification with reference tothe aecompanyingdrewngs in which.;

L The dome comprises rnnarily a crown outwardly. vAt their lower outer ends the pieces C to whichare also attached the horithere' are two sets, an upper set D and a lowersetE, forming a panel space between thesaxne. I e

The inclined ybars extending from the `trou-'nto the connecting pieces at the-outer edge-of the dome .arefchanneled, the side ianges B lof: the lchannel giving Aan aplnjplace, which adds to the e'ectiveness of .the dome in the matter ofappearance. By reason of these side flanges on the inclined the. channel, ,a suiiicienb depth is given to thechannel itself. to permit of lthe edges of the necessity for. `very accurateV fitting or cnt tmg of .the '-glass.
